Block-to-block hunt for NSW Lego thief

About $8500 of Lego, including highly-collectable items have been stolen from a toy store in the regional NSW town of Young.

The popular plastic brick toys were pinched at about 3.30am on Monday when a man broke into the Boorowa Street shop, before fleeing in a car, police say.

Officers want to speak to a man captured on CCTV who was hobbling around in a nearby car park at the time, and have publicly released the footage in the hope someone might recognise his "distinct way of moving".
